Specification of Letters Patent. Patented D131. 18, 1913.

Application filed July 13, 1912. Serial No. 709,195.

To all whom it may concern Be it known that I, TVILLIAM J. LESTER, a citizen of the United States, residing at Kearny, in the county of Hudson. and

,State of New Jersey, have invented certain new and useful. Improvements in Reducing or Regulating Valves; and I do hereby de clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertai-ns to make and use the same, reterence being had to the accom anying drawings, and to characters of re'ci'ence marked thereon, which form a part of this specifi' cation. I v

The present invention relates, generally, to improvements in valve mechanism; .and the invention refers, more particularly, to a novel construction of reducing valve for controlling and regulating the volume of fluid passed there-through.

' The present invention has for its principal object to provide a simple, easilyoperate'd and efl'ective construction of reducing valvemechanism adapted to permit the passage therethrough of a stream of fluid, the volume of which maybe regulated in various degrees from the maximum volume to the minimum volume easilyand quickly, and

-in addition to such regulation thev said valvemechanism is constructed to .shut-ofithe stream of fluid entirely when it is so desired.

Another object of the present invention is to provide a reducing valve-mechanism for controlling a stream-of fluid passedv therethrough which is so constructed as to readily indicate exteriorly of the valve-mechanism the proportionate degree of regulation of said. stream of fluid between the given maximum and minimum volumes which said valve mechanism will pass. a

,Other objects of the present invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of my present invention.

With the various objects of the present in vention in View, the said invention-consi ts in the novel construction of reducing valve mechanism hereinafter set forth; and, furthermore, the inventionconsists-in the-novel arrangements and combinations of the various devices and parts as well as in the details of the construction thereof, all of which will be hereinafter more tully'described in the following specification, and

then finally embodied in the clauses of the claims which are appended to and which tor n an essential part of this specification. The invention is clearly illustrated inthe accompanying drawings, in which Figure 1 is an elevation of one side of the novel construction of reducing valve mecha nism made according to and embodying the principles of the present invention; F ig.

2 is an elevation of the opposite side thereof; Fig. 3 1s atop or plan view thereof; and

Fig. 4c is 'an end elevation of the same; Fig.

5 'is a longitudinal vertical section of said novel construction of reducing valve mechanism, the same being illustrated in its-closed or shut-oft condition obstructing the passage of a stream of fluid therethrough; Fig. 6 is a similar vertical section of the same,

illustrating the valve mechanism in one of ciples of. the present invention, the J same comprising a valve casing 2' provided at each end with an interiorly screw-threaded opening -3 by means of which said valvemechanism may be connected in a lineof icing or the like.

valve-casin 2. and )referablv centrall lo-- cated between its ends, are the walls 4 of a' gate casing, the inner surface of said walls being tapered or'inclined outwardly, from the bottom to the top of said gatecasing s0 as'to provide a seat; The Walls 4 of said gate-casing are provided with an upwardly extending part 5 which is exteriorlv d1sposed with relation to said valve-casing 2.

tegrally formed inconnection with said This part 5 of saidgatecasing is provided with an exteriorly disposed screw-thread 6.

to said gate-casing are the interiorly dis posed screw-threads 7 of the flange or skirt 8 ofa capsnieinber 9, which serves to close Connected by means of said screw-threads 6 the upper end of said gate-casing. daid cap-member 9 is provided with a centrally disposed perforation or opening 10, and

2 upon its inner or under side with a socketportion 11. Arranged; within said gate-' --casing is a regulating gate-member 12, the,

walls 13. of which-are tapered at their exterior "face so as to, snugly engage the seat hfoi fhed byi thewalls 4 of said gate-casing.

Said iregulating gate-member .12 is provided at'its-lnw'er end with a chamber Orwell 14 which is'bounded by its walls 13 and is closed at its upper end. Extending .upwardly from the 'upper'end wall of said gate-member 12 is a spindle portion 15,

which passes through said perforation or opening 10 of said cap-member 9 so'as to be exteriorly presented above said cap-member. The upper free end of said spindle-portion 15 is provided with a reduced and squaredshank 16 upon which is secured, in any suitable manner, a handle-member 17. Sur:

rounding the interiorly disposed portion of said spindle-portion 15 is a coil or compression spring 18, one end of which is seated within said socket-portion 1 1 of said capmember 9, and'the other end of which bears against the end wallof said gate-member 12 to maintain the same properly seatedand operatively arranged in connection with said gate casing. The walls 4 of said gatecasing are provided with an inlet passage or opening 19 and an outlet passage or opening 20, the latter being oppositely disposed with relation to the former, but being'lo- -cated in a horizontal plane below the hori- -zontal plane of the former. The said inletv and outlet openings or passages respectively communicate with the respective open ends 3 of said valve-casing 2. The walls 13 of said gate-member 12 are provided, with a plurality of intake perforations or openings 21, 21. 21", 21, and 21, and the same respectively decreasing in size or diameter, and extending around -said wall 13=so as to lie in the plane of said inletopening'or passage 19, with which they may be respectively regis tered so as to establish vcommunication be tween the chamber or well 14 of said gatemember and one open end of said valvecasing 2. In like manner said walls 13 0f said gate-member 12are further provided with a plurality of exit perforations or openings 22, 22 22*, 22, and 22, and thesame above described are so disposed with rela-' tion to each other that the openings or permassi "be variously controlled between a minimum and maximum volume, according to the size of the selected opening of-said series of per- -'forationsor openings. registered with the respective inlet and outle't'passages 19 and 20. In order to'permit' theselection of any of said series of perforationsor openings in said gate-member 12 na registration with said inlet and outlet passages 19, and 20, and to afford a visible'me'ans', exterior'of saidvalve casing 2, whereby the position of said gate-member may be prop- -erly indicated when such perforations or openings are so properly registered, the ex-' tcrior surface of said flangejor skirt 8 of said cap-niembrt) is provided witha series of properly spaced and numbered, or otherwise indicated, graduations 23, one for each pair of perforations in said respective series of intake and exit perforations or openings, and anindicatedvgraduation 24 for indicating the shut-oft position of said gate-member 12, and connected with said handlemcmber 17, which operates orturns said gate-member 12, isan outwardly projecting arm 25 provided with a downwardly turned indicating pointer 26 which when registered with'an'y of said graduations indicates I the position of said gate-member-12. The

said walls 13 ofsaid gate-member'12 are provided with deadspaces 27 and 2734. e. unperforated, which when respectively registered with the respective inlet and outlet passages 19 and 20 block or shut-oft the passage of the fluid'through said regulating gate;member as indicated in Fig. diet the.

drawings,

'From the'abo've description of the present invention it will be evident that; the present invention provides-a very simple reducing or regulating valve-mechanism, which affords a quick and easy means for reducing or regulating the volume of fluid desired to be passed through said valve, or for shuttingoif entirely the passage of fluid therethrough, 'and owing to the convenient indicating de-- vices connected with said valve-mechanism it may be quickly and easily ascertained, by a glance at the exterior of said valve, in just what position the regulating gate-member'is set at any given time, or in the operation of the gate-member itself.

I am aware i that some changes may be made in the various-details and arrangement of the devices and parts of theprcscnt invention without departing'from the scope thereof. Hence, ll do not limit my invention to the exact arrangements and combinations of the various devices and parts as herein set forth, and as illustrated in'the accomtable gate-member mounted within said panying drawings, nor do Iconfine myself to the exact details of the construction of the said parts. i
